The array of sought-after features of LiCoO<sub>2</sub> depends on its synthesis method. In this work we synthesized and characterized a nanocrystalline LiCoO<sub>2</sub> oxide obtained with a wet chemistry synthesis method. The oxide obtained was a homogeneous powder in the nanometric range (5-8 nm) and exhibited a series of improved properties. Characterization by FTIR and UV-Vis techniques led to identifying citrate species as main products in the first step of the synthesis process. X-ray diffraction (XRD), Raman, and transmission electron microscopy (TEM) characterizations led to identifying a pure crystalline phase of the synthesized LiCoO<sub>2</sub> oxide. Steady state electrical characterization and solid-state impedance spectroscopy determined the high conductance of the synthesized oxide. All these features are desirable in the design of cathodes for lithium ion batteries.</p> ER -
